The New Hampshire House of Representatives has taken significant steps toward cannabis reform by passing bills that legalize marijuana, decriminalize psilocybin for adults, and expand medical cannabis access. These measures were approved in a session held on March 26, 2025.
House Bill 198, introduced by Rep. Jared Sullivan (D), allows adults aged 21 and older to possess up to two ounces of marijuana flower, 10 grams of concentrate, and 2,000 milligrams of THC in other cannabis products. However, retail sales and home cultivation of marijuana would still be prohibited, and consuming marijuana on public land would remain illegal. The bill passed with a vote of 208-125.
Ahead of the vote, Rep. Sullivan highlighted the need for reform by stating, “It is 2025. Let’s stop arresting people and ruining their lives for possession of cannabis, something that many states in the country have already legalized.” He noted a general agreement on the need to legalize cannabis, though discussions continue on how to regulate its sale.
In addition to marijuana legalization, the House approved HB 528, sponsored by Rep. Kevin Verville (R), which would reduce penalties for psilocybin offenses. Under this legislation, a first offense would be classified as a violation with a fine of no more than $100. Subsequent offenses would be misdemeanors with fines of up to $1,000 but would not carry jail time. Sales and distribution of psilocybin would remain illegal, affecting only personal use and possession for adults 18 and older.
Rep. Verville described the passage of this bill as “an historic, albeit small first step on our journey to correct 60 years of demonstrably failed policy on psychedelics.” He expressed hope that the New Hampshire Senate would agree with the House’s position and that the governor would support the bill.
The House also passed HB 190, introduced by Rep. Heath Howard (D), which increases the medical marijuana possession limit for patients and caregivers from two ounces to four ounces. The current 10-day purchase limit would also rise to four ounces.
These cannabis-related bills were passed as part of the chamber’s consent calendar without debate, and they now move on to the Senate for further consideration. A related proposal, HB 380, is also set for discussion in the House this week.
